I converted my 35' sailboat "Heron" last year. I tried to keep it simple. I left all the gear at the mast, including the clutches; but led the lines to a second set of clutches on the cabin-top. If the ones at the mast are open the ones in the cockpit hold the lines. My description with pictures can be found here from a previous thread;
I did it for safety as I am getting older, for making single handed sailing easier and sailing with newbie friends and kids more relaxing. I also have an autopilot. I installed that first a few years ago and it worked fine when going forward (also with jack lines and harness). But this upgrade gets me out more often.
